GE Aerospace, PHI Aviation to Launch Pilot Program for CT7-8 Digital Engine Health Monitoring Tool

March 08, 2023

HAI HELI-EXPO, ATLANTA – GE Aerospace and PHI Aviation will be launching a pilot program featuring GE’s new digital engine health monitoring technology for CT7-8 engines, through its industry-leading fleet support team. The objective of the program is to refine and expand the tool, eventually making it available to operators of CT7-8 and other CT7 variants.

The CT7-8 is the exclusive powerplant for Sikorsky’s S-92 helicopter. PHI was the S-92 and CT7-8 launch customer and today operates 34 S-92s. PHI’s missions include flights for offshore energy, onshore mining, marine pilot transfer, air medical, SAR, and technical services.

“PHI and GE have a longstanding partnership, and we’re excited to continue building on that foundation to develop the next generation of digital engine health monitoring technology,” said John Ellyson, Director of Maintenance for PHI Aviation – Americas. “This technology will not only transform how we understand trends and behaviors of engine performance but will also set the stage for the future of proactive maintenance support.”

GE’s digital engine health monitoring tool combines robust engine analytics capabilities with original equipment manufacturer experience to produce actionable insights which keep customers’ aircraft ready for the next mission. The analytics identify proactive maintenance needs, provide customized maintenance recommendations and more, all in pursuit of improved performance, reliability and lower operating costs.

“GE Aerospace is proud to work with PHI to launch this pilot program,” says Elissa Lee, Director of GE Aerospace's Commercial Turboshaft Engines. “Our goal is to help our customers get the most out of their engines, and this program enhances support of our commercial rotorcraft engine customers. As an OEM, GE carries both engine expertise and proven analytics experience to deliver a tool tailored to our rotorcraft customers’ needs.”

The CT7-8 engine combines advanced, state-of-the-art technology with mission-proven T700 design architecture. Designed for increased durability with commercially proven components, these powerful engines feature Full Authority Digital Electrical Control (FADEC) for better cockpit information and reduced pilot workload. The CT7-8 proudly powers a variety of multi-role aircraft including the S-92, AW101, and NH90.
